Karakteristik Bio-Oil Hasil Pirolisis Ampas Tebu

Abstract

Bagasse (Saccarum oficinarum L) is a waste of sugar mills that can be utilized for a variety of chemicals. The purposes of this study are to determine the percentage of compounds and physical properties of bio-oil, to determine the effect of variations of particle size and heating rate on the yields of bio-oil. Pyrolysis has been carried out in a reactor made of steel pipe type 5737 with dimension: diameter 7.62 em and a length of 3 7 cm.. The reactor was inserted into the furnace with a diameter of 15.24 em and a length of 40 em. One hundred and fifty grams of bagasse (Saccarum oficinarum L) has been inserted into the reactor without the presence of oxygen at atmospheric pressure. Pyrolysis has been carried out at the particle size of (-20+25) mesh, (-25+30) mesh, (-30+35) mesh, (- 35+40) mesh, and -40 mesh with electrical voltage of 100, 105, 115, and 120 volt. Produced of bio-oil has the following properties: brown color, pH of 2.96 to 3.03, viscosity of 1.3306 to 1.5101 cp, and density of 1.03 to 1.5 g/mL. The largest content of the compound is acetic acid (59, 72%). The highest yields percentage of the particle size is (40,32%) on (-20+25 mesh) with the highest yields percentage of electrical voltage is 38,82% on 105 volt.Keywords : Bagasse, acetic acid, bio-oil, pyrolysis, yields

Potensi Produksi Bio-Oil dengan Metode Pirolisis Katalitik Menggunakan Katalis Zeolit dari Ampas Tebu: Studi Literatur

“…Dalam 100 ton tebu yang diproses dalam sebuah pabrik gula, akan menghasilkan sekitar 30 ton ampas tebu basah [11]. Sejauh ini, hanya 30-50% ampas tebu yang sudah dimanfaatkan antara lain; sebagai bahan baku produksi bioetanol, dibakar untuk menghasilkan uap pada pembangkit listrik, bahan baku kertas, bahan baku industri kanvas rem, industri jamur, dan lain-lain, sedangkan sisa residu lainnya belum termanfaatkan secara optimal [11], [19].…”

“…Ref. [19] juga melakukan penelitian dengan variasi diameter partikel yaitu (-20+25), (-25+30), (-30+35), (-35+40) dan -40 mesh serta kecepatan laju pemanasan yaitu 100, 105, 110 dan 120 volt. Didapatkan yields tertinggi pada diameter partikel terkecil yaitu (-20+25) mesh sebesar 40,32 %.…”

Improving the Quality of Bio-Oil Produced from Rice Husk Pyrolysis by Extraction of its Phenolic Compounds

“…Special Task Force for Upstream Oil and Gas Business Activities of Republic Indonesia (SKK Migas) (ESDM, 2016) showed that the petroleum reserves are estimated to decrease from 4.3 billion barrels in early 2004 to 3.7 billion in 2014. Indonesia's alternative fuel consumption in 2011-2015 is 4.52 million kilo liters of biodiesel, 2.78 million kilo liters of bioethanol, 1.8 million kilo liters of bio-oil, and 9.84 million kilo liters of biofuels (Erawati et al, 2013). Depletion of the fossil fuels reserves made the development of alternative fuels such as bio-oil urgently needed.…”

“…Bio-oil is an inorganic liquid which produced by pyrolysis process (Erawati et al, 2013). Bio-oil can be produced from biomass.…”
